+ and Fe3+on leaching MnO2 in MnO2-FeS2-H2SO4 leaching system FENG Yali1, ZHANG Xu1, LI Haoran2, CAI Zhenglei1 (1. Civil and Environmental Engineering School, University of Science and Technology...: In the MnO2-FeS2-H2SO4 leaching system, through the variation of the concentration of Mn2+ in solution, MnO2 leaching rate and leaching efficiency were investigated and mionitored with different concentrations of H......
from complex sulfide concentrates was investigated via chlorination roasting followed by water leaching. A reaction process is proposed on the basis of previous studies and the results of our preliminary experiments. During the process,various process parameters were studied,including the roasting temperature,the addition of NH4 Cl,the roasting time,the leaching time,and the liquid-to-solid ratio......
